SOA MADE EASY WITH SAP

Service-oriented architecture (SOA) is a blueprint for an adaptable, flexible, and open IT architecturefor developing services-based, modular business solutions. SAP makes it easy to adopt SOA enabling companies in diverse industries to quickly differentiate their businesses and optimizeprocesses in their business networks. SAP enables businesses to adopt SOA at their own pace as

part of their SAP solutions.

At the heart of SAP's open-standards approach to SOA is the concept of enterprise services interfaces, which provide business processes or business process steps that can be used to composebusiness scenarios while ensuring business integrity and ease of reuse. SAP designs and implementsenterprise services in such a way that they safeguard semantic harmonization and businessrelevance.

Using enterprise services, you can leverage SAP solutions in conjunction with partner solutions andhomegrown solution landscapes to build new, flexible, and innovative solutions based on a consistentintegration concept.

SAP and our partners can help your IT organization adopt SOA in a low-risk manner by deliveringSOA-based technology, service-enabled applications, and prepackaged enterprise services grouped

as business scenarios. SAP delivers SOA seamlessly via the service-enabled software (SAP BusinessSuite) and SOA-based, open technology platform (SAP NetWeaver). SAP consultants deliver servicesthat complement SAP applications and accelerate SOA adoption.

We offer comprehensive methodology for design and development as well as operational SOAgovernance, modeling and implementation guidelines for service developers. Moreover, SAP'senterprise services follow the enhancement package concept, so you can add new functionalitycontinuously, without extended upgrade cycles.

Web Services and Enterprise Services

Enterprise services allow you to leverage SAP solutions to include a wide range of composite

applications provided by customers and partners to build new, flexible, and innovative solutions. SAPpublishes all enterprise services that support SAP Business Suite functionality at the EnterpriseServices Workplace in the SAP Developer Network (SDN).

The following characteristics differentiate enterprise services from regular web services:

Business semantics: Enterprise services are structured according to a harmonized enterprisemodel based on business objects, process components, and global data types (GDTs). Theyare defined using an outside-in approach: common business rules and know-how, rather thanSAP-specific implementations, are the guideline for defining the business content of SAPapplications.

Quality and stability: Enterprise services safeguard a stable interface for future versions(backward compatibility). Their behaviour, prerequisites, dependencies of usage andconfiguration possibilities are well documented.

Standards: Enterprise services are based on open standards. The interfaces are describedaccording to WSDL. They are created by using global data types which are based onUN/CEFACT CCTS (Core Component Technical Specification). B2B enterprise services aredefined in compliance with e-business standards, where applicable.

There are different application areas for enterprise services, for example application-to-application(A2A) and business-to-business (B2B) integration or user interfaces.

Enterprise services are identified at a business level that supports business processes. With theEnterprise Services Community (ESC), SAP actively engages customers and partners in the processof identifying and defining enterprise services. In this respect, SAP continuously analyzes all businessprocesses from the perspective of the main key business drivers for SOA: business processautomation, business process innovation, user efficiency, and deployment flexibility. As a result, SAP

has defined and productized -- and continues to do so -- a comprehensive set of enterprise services tohelp customers, partners, and developers build flexible applications on top of the stable core of theSAP Business Suite. These services are published in the Enterprise Services Workplace.

SAP has developed an advanced meta model and governance process to define and model enterpriseservices. Key concept is the business object model. Each enterprise service is assigned to a businessobject, representing a well-defined business entity or document. Each business object is assigned to aprocess component. Process components are pieces of software covering a well-defined set ofbusiness tasks which belong logically together and are usually executed in the same department.

All identified services were modeled by SAP architects and developers in the Enterprise ServicesRepository (ES Repository), which is provided by SAP NetWeaver Process Integration or SAPNetWeaver Composition Environment since release 7.1.

Logically, an enterprise service is a service operation, derived from a standardized interface pattern,which contains operation names such as create, read, update, orcancel,and incorporatescommunicational patterns. It is described as a WSDL scheme in the ES Repository. The consumingapplication and the back-end systems communicate through messages that manage the input andoutput of the service operation data fields. If mediation capabilities like mappings, messageorchestration and an extended receiver determination are needed, you might implement such kind of

scenarios using SAPs SOA Middleware solution which is SAP NetWeaver Process Integration.Service operations can be grouped by service interfaces. In this document, service interfaces andservice operations are often used as synonyms for particular enterprise services.

For example, the SAP ERP process component Sales Order Processing provides the enterpriseservice interface Manage Sales Order In,among others. From this interface, you can access theenterprise service operation Create Sales Order, which operates on the business objectSales Order.

The SOA governance process takes care that all enterprise services are defined according to thegiven rules. This safeguards consistency, standards compliance, harmonization of semantics andreuse across all SAP solutions. Based on the semantic definition, each enterprise service is subject toa harmonized service cut, an aligned naming, consistent documentation, a common servicedescription and service orchestration. In result, enterprise services represent a common language ofbusiness at the required level of granularity.

With enterprise services, you can:

Enable both process and system integration in A2A and B2B scenarios, which you can model,implement and execute with SAP NetWeaver Process Integration and SAP NetWeaverBusiness Process Management.

Simplify and streamline user interaction through open consumption of innovative userinterfaces, such as mobile devices and interactive forms, a.k.a. A2X scenarios.

Leverage accelerated innovation through user and case-centric innovative processes (A2X) thatcan be implemented using SAP NetWeaver Composition Environment, while safeguardinghigher process efficiency and reducing costs.

See the glossary of this document for a definition of the technical terms used above, or see thedocuments available at the Getting Started area of the SOA Knowledge Centerat the bottom of theSOA home page in SDN.

Enterprise Services Bundles

Enterprise Services (ES) bundles build the comprehensive portfolio of business scenario descriptionsthat are SOA-enabled by solutions and enterprise services shipped by SAP today. By reading ESbundles documentation, you will be able to understand the impact of SOA on your business processeseven without profound knowledge about SAP solutions or technology.

Each ES bundle refers to a set of enterprise services that support a particular business process andare made available as part of the SAP Enhancement Packages for SAP Business Suite solutions.

ES Bundle documentation provides:

exemplary use cases of how enterprise services help implement certain business processsteps,

documentation of how to extend and reconfigure processes in a business scenario,

explanations of the relevant business scenario, processes, and roles involved and

guidance about how to put the services to work.

ES bundles help design composite applications using SAP NetWeaver's enterprise servicesdevelopment and modeling tools.

IMPLEMENTING SOA

An ES bundle is not a pre-packaged installation or installable entity. You need to download and installthe respective Enhancement Package or Support Package of the relevant SAP Business Suiteapplication to make the enterprise services available in your system.

Please note:You may have to activate Business Functions to make certain enterprise servicesavailable in your system. ES Bundles cannot be activated. They are available in the softwarecomponents you install on your system.

For further details on the SOA enablement of SAPs applications and on the consumption of enterpriseservices, please refer to the detailed Master Guides, available at the SAP Service Marketplace (e.g. athttp://service.sap.com/erp-ehp)and the SAP Community Network(http://www.sdn.sap.com/irj/sdn/soa).

GLOSSARYProcess Component

Process components can be seen as the building blocks of each SOA solution. They are modular,context independent, reusable pieces of software that expose their functionalities as services. Aprocess component contains at least one business object.

Business Object

A business object is a logical object of significance to the business. It represents a class of entitieswith common characteristics and common behavior describing well defined business semantics.Business objects are used to model a business process. They therefore represent a specific view onbusiness content.

Web Service

A standardized service encapsulating the functions of an application in a way that other applicationscan locate and access the service. A Web service can be called directly in a peer-to-peer fashion.

Global Data Type

An SAP-wide defined data type with meaning, structure, and values based on industry standardswhere available.

Enterprise Service

Enterprise services are interfaces designed according to the following governance principles:

Business semantics: Enterprise services are structured according to a harmonized enterprisemodel based on business objects, process components, and global data types (GDTs).

Quality and stability: Enterprise services safeguard a stable interface for future versions(backward compatibility). Their behavior, prerequisites, dependencies of usage andconfiguration possibilities are well documented.

Standards: Enterprise services are based on open standards. The interfaces are describedaccording to WSDL. They are created by using global data types which are based onUN/CEFACT CCTS (Core Component Technical Specification).

Service Operation

The smallest, separately-callable function within a service interface, described by a set of data typesused as input, output, and fault parameters serving as a signature. A service operation is grouped byservice interfaces.

Service Interface

A named grouping of service operations, based on standardized interface patterns, such as create,update, orcancel

Enterprise Services Bundle

An ES bundle is a piece of documentation that refers to a set of pre-packaged enterprise services,which support a particular business process and are made available as part of the SAP EnhancementPackages for SAP Business Suite solutions. ES bundle documentation provides exemplary use cases

of how enterprise services help implement certain business process steps, advice on how to extendand reconfigure processes in a business scenario, explanations of the relevant business scenario,processes, and roles involved, plus guidance about how to put the services to work.

Communicational Patterns

Typical communicational patterns used by enterprise service operations are:

Request/confirmation: means that messages are sent back and forth and that the statemaintained by the service may change.

Query/response: means that messages are sent back and forth but that the state maintained bythe service does not change.

Notification: means that a service sends a message that contains a notification of an event.

Information: means that a service sends a message containing other information.

A2X, A2A, B2B

Data exchange patterns for enterprise services:

A2X: Application To X users, created for unforeseen extensions of the SAP software

A2A: Application To Application, data exchange between two applications in one business

process platform within the same enterprise B2B: Business To Business, data exchange between two business process platforms across

enterprise boundaries

SAP NetWeaver Enterprise Services Reposito ry

SAP NetWeaver Enterprise Service Repository (ES Repository) is the central repository whichcontains the definition of all enterprise services and all models. Ideally, there is exactly one ESRepository in a system landscape. The ES Repository plays the role of the central business processintegrator. The enterprise services, business objects and business processes are defined andmodelled centrally.

WSDL

WSDL is an XML-based description of Web services.

WSDL from ES Reposi tory

WSDL from ES Repository is an XML-based description of Web services containing structuralinformation. This WSDL does not contain the binding information of a service end-point.

WSDL from Backend

WSDL from Backend is an XML-based description of Web services containing binding information.Thus the WSDL contains all necessary information to actually call and consume an enterprise service

Message Type

The reference to a data type used to define the data exchange between a service provider and itsconsumer. An operation comprises one or several message types such as requests, responses, anderrors.

Technical NameThe technical name is derived from the service operation name according to SAP naming conventions.It is the name for the service operation defined in ES Repository.

Composite Application

A composite application is an application that uses data and functions provided as services byunderlying applications, and combines these into user-centric processes and views, supported by itsown business logic and specific user interface.

Services Registry

The Services Registry is a registry for Web services. Located centrally within an SOA landscape, itcontains entries for all services and service definitions in that landscape, with references to theservices relevant WSDL metadata and to the locations of the callable service endpoints. The

registered services are classified using semantic-rich classification systems to enable browsing ofservices by classification.
